SIGHT-FEED oit-CUP.

SPECIFICATION forming part of Letters Patent N o. 639,293, dated December 19, 1899.

Application tied August 16, 1897.

To @ZZ whom it may concer/t:

Be it known that I, HENRY RITTER, a citivzen of the United States, residing at Cincinnati, in the county of Hamilton, in the State of Ohio, have invented a certain new and useful Improvement in Sight-Feed Oil-Cups, of

which the following is ades'cription, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to that class of sightfeed oil-cups in which the oil is contained in a 'reservoir and delivered by gravity therefrom through a sight-feed chamber beneath the reservoir, said delivery being controlled t5` by a central valve-stem extending vertically through the reservoir and projecting above its upper end.

The novelty of myinvention consists in certain details of construction and arrangement zo of parts, which will be hereinafter set forth, and particularly pointed out in my claim.

In the accompanying drawings, Figure l is` au exterior view of my improved oil-cup; and Fig. 2, a vertical central section, the valve z 5 controlling the delivery of oil being in open position in both views.

The same letters of reference are used to indicate corresponding parts in the two views. The body of the oil-reservoir consists of a 3o heavy glass cylinder A, seated at its lower end in the bottom cap or base B and having the top cap C iittingy upon its upper end. Packing rings or gaskets D D, of cork or other suitable material, are interposed between the ends of the cylinder A and the caps B C to form tight joints. The lower cap Bis provided with a depending central extension E, which is exteriorly threaded and has screwed upon it the member F, containing the sight- 4o feed chamber, in this instance consisting of a glass cylinder G, supported within the member F and observable through sight-openings in the sides thereof. The internal bore of the member F, within which fits the sightfeed glass G, communicates at its lower end with an oil-delivery passage I, and the glass G is seated upon the shoulder formed at the junction of this passage with the lower end of the larger bore and confined between this 5o shoulder and the lower end of the depending extension E of the cap B, packing-rings J J Serial No. 648,396. (No model.)

being interposed between the opposite ends of the glass Gand the adjacent metal.

The cap B has formed integral with it a central vertically-extending hollow stem or tube K, which extends through a central hole in the top cap C and projects above the latter. The internal bore of this stem K comm unicates at its lower end with a vertical oil-delivery passage L, extending downward through the cap 6o B and its extension E and terminating at its lower end in a nozzle M within the upper end of the sight-feed glass G. A series of orifices N open through the walls of the stem K into the internal bore thereofl to permit the oil within the reservoir to pass into said stein and thence downward through the same and through the passage L and drop from the nozzle M through the sight-feed glass G into the delivery-passage I, aud the lower end of the 7o internal bore of the stem K at its point of junction with the smaller passage L forms a seat for the lower end of the valve-stem O, which extends vertically through the hollow stem K and projects above the upper end thereof. The middle portion of the valvestem O is of substantially the same diameter as the interior of the hollow stem K; but the valve-stem is reduced in diameter both above and below this middle portion, the reduction 8o below affording an open space around the stem for the inlet of the oil from the oil-reservoir, while the reduction above affords room for a spring P, which is coiled around the valvestem and rests at its lower end upon the shoulder formed by the upper end of the enlarged portion of the stem and is confined at its upper end by the cap-nut Q, which is screwed upon the exteriorly-tln'eaded upperendof the stem K. ThespringPexertsaconstantdown- 9o ward pressure upon the valve-stein and tends to seat its lower end against the valve-seat at the upper end of the passage L to cut off the delivery of oil. The valve-stem O extends upward through the nut Q and has rigidly secured to its upper end a rectangular block S, upon which is pivoted a lever R, whose lower end is forked and straddles said block. The pivotal point of the lever Ris so located that it is farther removed from the lower end Ioo of the lever than from the opposite sides of the lever, with the result that when the lever is turned to the vertical position shown in the drawings it will serve to lift the valvestem O and unseat its .extreme lower end to permit the delivery of oil, while when the lcver is turned vto horizontal position it will permit the spring P to press the stem O downward far enoughto seatits lowerend and cut oft the delivery of oil. The rate of feed of oil when the valve is open may be regulated by the nut Q., by screwing which upward or downward upon the stein K the valve-stein O may be adjusted to any desired position, so that when the lever R is in vertical position the valve controlling the delivery ot' the oil will be opened to any desired degree.

The cup is provided with the usual slide T, which rests upon the upper surface of the cap C and at its inner end surrounds the stem K, which slide controls the lling-hole U of the cup, while resting upon the upper surface of the inner end of the slide is the lower horizontal end of a spring V, the upper end of whose vertical portion is bent inwardly and engages notches formed upon the surface of the nut O, the engagement of the spring with these notches serving to hold the nut in any of its adjusted positions. A n ut W, screwed upon the threaded upper end of the stem K, rests upon the upper. surface of the horizontal portion of the spring V and serves to bind the upper and lower caps and glass cylinder of the cup together. The upper end of the stem K is tiattened or cut away at one side, Yand the opening in the lower end of the spring V, through which the stem K passes, is shaped to fit this attened side of the stem and serves to prevent the movements of the slide P being4 transmitted to and loosening the nut W.

Seat-ed in a bore in the upper end of the lee ee9;293

ver R is a spriu gpressed plug X which bears at its lower end upon the u pper surface of the valve-stein or its block S and serves to aid in yieldingly holding the lever R in its vertical and horizontal positions.

Having thus fully described my invention, I claiin- Y l.. ln an oil-cup, the combination of a cylinder, a cap having a central hole, a base having a hollow stem provided with a screwthreaded portion projecting up through said holein the cap, and also provided with a valveseat and oil-inlet orice,a locking-nut screwed onto said stem and securing the cap-cylinder and base together, a spring-actuated valve in--said hollow stem adapted to seat on vsaid valve-seat, a valve-stein therefor, an adjusting-nut Q screwed on the upper end of the hollow stem and having a circular hole in which a cylindrical portion of the valve-stem works so that the n ut is rotatable around said valve-stem, and a lever, pivoted to the valve'- stem and Working on said adjusting-nut, for lifting said valve-stem, and means carried by said lever for holding it in its different positions, substantially as described.

2. In au oil-cup, the combination of the hollow stem, a valve-stem sliding therein carrying a valve, an operating-lever pivoted to said valve-stem, a nut on said hollow stem on which said lever works, and a spring-pressed plug carried by said lever and held by its spring in contact with the valve-stem, substantially as described.

HENRY RITTER.
